The Bears have signed nose tackle Bruce Gaston off the Packers’ practice squad, sources told the Sun-Times on Saturday. He’s expected to play Sunday in Detroit against the Lions.

Gaston, who is 6-2, 310 pounds, appeared in two games this season for the Packers, making one tackle. The second-year lineman was waived on Oct. 3 and re-signed to the Packers’ practice squad three days later.
